Problems solved by technology

For example, although Japanese Patent Laying-Open No. 4-5213 and Japanese Patent Laid-Open No. 6-219923 have proposed cleansing compositions containing water-soluble compounds having specific nonionic surfactants and hydroxyl groups, liquid oil, and water, these Most of the compositions have a viscosity of 300mPa·s or more, and there are problems such as poor affinity with oil-based cosmetics (especially oil-based mascara), or poor floating properties
On the other hand, when it is used on wet skin in an environment such as a bathroom, a solid liquid crystal structure will be formed due to the mixing of water, and the cleaning ability of cosmetics will be greatly reduced due to stickiness, or the cleansing ability of cosmetics will be greatly reduced due to white turbidity. The cleansing ability of oil-based cosmetics, etc. cannot be said to have sufficient water resistance, so it cannot fully meet the needs

Embodiment 1～29、 comparative example 1～18

[0062] Make-up remover cosmetics with the compositions shown in Tables 1 to 6 were produced, and the appearance, properties, cosmetic shedding, transmittance after mixing with water, cosmetic shedding, rinsing properties, and overall performance of the obtained makeup remover cosmetics were evaluated. The results are shown in Table 1 to Table 6.

[0063] Manufacturing method

[0064] The ingredients (A), (E) and other ingredients are heated and completely dissolved in the ingredient (C), and then the ingredients (B) and (D) are added and mixed uniformly to obtain a makeup remover cosmetic.

[0065] Evaluation method

[0066] (1) Appearance:

[0067] At 25°C and 40°C, use a turbidity meter (digital colorimeter mini photo5; Φ10mm glass cuvette; manufactured by Sanshen Industry Co., Ltd.) at a wavelength of 530nm and use purified water as a reference to measure the transmittance. When the transmittance of a 0.001 wt% titanium oxide suspension aqueous solution is “transparent”, the tr...

[0107] Make-up remover cosmetics with the compositions shown in Table 7 and Table 9 were prepared in the same manner as in Examples 1-29. The appearance, properties, and cosmetic shedding of the resulting make-up remover cosmetics, the transmittance after mixing with water, the shedding of cosmetics, and rinse Sex and overall performance. The viscosity of makeup remover cosmetics was measured by the following method. The results are shown in Table 8 and Table 10.

[0108] Viscosity measurement

[0109] At 25℃, use B-type viscometer (2 # Rotor, 30rpm) was measured. When the pointer of the viscometer exceeds the range, it can be used as needed. 3 # , 4 # Rotor.

[0118] Make-up remover cosmetics of the composition shown in Table 11 were produced in the same manner as in Examples 1-29. The appearance, properties, cosmetic shedding condition of the obtained make-up remover cosmetics, permeability after mixing with water, cosmetic shedding condition, and rinsing properties were similarly analyzed. The storage stability of makeup remover cosmetics was measured by the following method. The results are shown in Table 11 together.

[0119] Storage stability

[0120] 50 g of each make-up remover cosmetic was stored at 0°C and 5°C, and the appearance after one week was visually evaluated and indicated by the following standard.

[0121] ○: No precipitate, transparent

[0122] ×: Precipitates are precipitated, or the whole is turbid due to the presence of precipitates.

Abstract

The invention provides a water-resistant cleansing preparation which takes the form of a transparent liquid and does not cause lowering in the cleansing power or deterioration in the appearance or the feelings in use even when contaminated with water, specifically, a transparent liquid cleansing preparation which consists of a composition comprising the following components (A) to (D) and does not turn cloudy even when 50 parts by weight of water is added per 100 parts by weight of the composition: (A) at least one nonionic surfactant selected from among (a) monoglycerol fatty acid esters wherein the fatty acid residue has 12 to 18 carbon atoms, (b) polyglycerol fatty acid esters wherein the fatty acid residue has 12 to 18 carbon atoms, (c) isostearyl pentaerythryl glyceryl ether, and (d) liquid nonionic surfactants having polyalkylene glycol chains and exhibiting IOB of 0.75 to 1.05, (B) a nonionic surfactant except the component (A), exhibiting IOB of 1.1 or above, (C) a liquid oil component, and (D) at most 12% by weight of water.

Description

Technical field [0001] The present invention relates to a makeup remover cosmetic, in particular to a makeup remover that is transparent, beautiful, liquid, has excellent cleansing ability, and does not cause white turbidity even when the skin is moistened with water. cosmetic. Background technique [0002] At present, cleansing makeup remover cosmetics that are used by rinsing or wiping with water include products in the form of cream, emulsion, gel, solution, etc. with oil ingredients. They usually use non-ionic surface active ingredients with oil ingredients and water. It is made by emulsifying or dissolving the agent (for example, Japanese Patent Application Laid-Open No. 3-161428). [0003] However, when the existing oily makeup remover cosmetics are used on the skin moistened with water, due to the presence of water, they will form emulsions or suspensions, appearing white turbidity, and make the appearance worse, and significantly reduce the oily dirt The cleaning ability ...
